It is very sad for people who find themselves part of a rigid system of thinking, to come to awareness, yet be unable to deal with it for fear of ostracation.
Somehting similr happend to me in 1968. Prior to that I was basically a social conformist, probably not dissimilar to George Bush. Then I went to an anti-Vietnam rally in Trafalgar Square, London. I wasn't against the war, as such, communism was the dark evil and neded to be defeated. I was strongly opposed to the use of Napalm and its effects on children.
At first, all I could see were a lot of throughly respectable people, many dressed in business suits. No chanting, no violence and no drugs.
Then all hell broke loose. The following day, a photo appeared on the front page of the Daily Express, a young girl on the ground, shielding her face, while a burly policeman stood over her with his trunchon aimed at her face. Even today, children in school, taught social history, are told that the 1968 rally was a demo by a bunch of long haired, dirty communist types who wanted to overthrow the established order.
It caused me to walk out of my school at the first opportunity, 2 years later. So, I not only lost that part of my education I also lost all the social connections which go with it. I can't say it put a barrier between me and my family, that was already there. I was an effininate queer. But up to the last time I saw them that was one of the principal sources of criticism. I know this is the reason my nephews and nieces and my younger sister will never have any contact with me.
I had to struggle. I had no life experience at all. For a time I went right down, even living on the street. My GP, shortly after I ment him 20 odd years ago, reviewed my notes and told me I had had every opportuity but had thrown it away.
I have a lot of sympathy for your Mormon friend. I have equal sympathy for others in similar situations, Muslims, Hindus and such.
For my part, I can't even concieve of continuing to support what I knew and know to be utter lies. I can't ever support war. I know people are equal. That each of us has an exactly equal right to be here.
We can only hope that those with the intelegence and conscionce to know that these cults, religious, political, social can develop the courrage to take a stand for what they know to be the right thing to do.
It won't make a blind bit of difference, in the larger scheme of things. But it will, at least, bring these people the personal satisfaction that they have, as far as possible, done no harm.
